Together 3 friends watched 411 short videos. Kelsey watched 43 more than Ekon. Ekon watched 17 less than Uma. How many videos did Kelsey watch?

Let U = the number of videos Uma watched

Ekon = U - 17

Kelsey = (U - 17) + 43 = U +

<<(-17)+43=26>>26 U + U - 17 + U + 26 = 411 3U + 9 = 411 3U = 402 U = <<134=134>>134 Kelsey = 134 + 26 = <<134+26=160>>160 videos Kelsey watched 160 videos. #### 160 Tall Tuna has twice as many fish as Jerk Tuna. If Jerk Tuna has one hundred forty-four fish, how many fish do they have together? If Jerk Tuna has one hundred forty-four fish, then Tall Tuna has 2*144 = 288 fish Together, they have 288+144= <<288+144=432>>432 fish #### 432 Tedra is harvesting his tomatoes. He harvests 400 kg on Wednesday, and half as much on Thursday. He harvests a total of 2000 kg on Wednesday, Thursday, and Friday. How many tomatoes of the number he harvested on Friday are remaining if he gives away 700kg of them to his friends? Tedra harvests 1/2 * 400 kg = <<1/2*400=200>>200 kg of tomatoes on Thursday. Tedra harvests 2000 kg - 400 kg - 200 kg = <<2000-400-200=1400>>1400 kg of tomatoes on Friday. After giving away tomatoes to his friends, he is left with 1400 kg - 700 kg = <<1400-700=700>>700 kg of tomatoes. #### 700 The tornado picked up the Smith's car and transported it 200 feet in the air before dropping it into the neighbors' pool. Also in the pool was a lawn chair that had been blown twice as far as the car had been transported. And the pool also contained a birdhouse that had flown through the air three times farther than the lawn chair had been blown. How far, in feet, far had the birdhouse flown? The lawn chair was blown twice as far as the car, or 2*200=<<2*200=400>>400 feet. The birdhouse had flown 3 times farther than the lawn chair had been blown, or 3*400=<<3*400=1200>>1200 feet. #### 1,200 In the school election, Eliot got twice as many votes as Shaun, and Shaun got 5 times as many votes as Randy. If Randy got 16 votes, how many did Eliot get? Shaun got 5*16=<<5*16=80>>80 votes Eliot got 80*2=<<80*2=160>>160 votes #### 160 Linda makes $10.00 an hour babysitting. There is a $25.00 application fee for each college application she submits. If she is applying to 6 colleges, how many hours will she need to babysit to cover the application fees? The application fee is $25.00 per college and she is applying to 6 colleges so that's 25*6 = $<<25*6=150.00>>150.00 She makes $10.00 an hour babysitting. Her application fees total $150.00 so she needs to work 150/10 = <<150/10=15>>15 hours to cover the cost #### 15 A yearly book sale is held in school where students can sell their old books at a cheaper price. Two-fifths of Lovely's books can be sold for $2.50 each and the rest for $2 each. How much will Lovely earn if all 10 books were sold? Lovely will sell 10 x 2/5 = <<10*2/5=4>>4 books for $2.50 each. She will sell 10 - 4 = <<10-4=6>>6 books for $2 each. Her earnings for the 4 books at $2.50 will be $2.50 x 4 = $<<2.5*4=10>>10. Her earnings for the 6 books for $2 each will be $2 x 6 = $<<2*6=12>>12. Thus, Lovely's total earning if all 10 books are sold is $10 + $12 = $22. #### 22 After a visit to the newly opened aquarium, 40 percent of the aquarium visitors fell ill from a mysterious disease. If there were 500 visitors, how many of them did not fall ill? If there were 500 visitors, and 40% of them fell ill, the number of visitors who fell ill is 40/100*500 = <<40/100*500=200>>200 people The number of visitors who did not get ill is 500-200 = <<500-200=300>>300 #### 300 During the most recent voyage of the Starship Conundrum, the spacecraft traveled from Planet X to Planet Y in eight hours less than twice the number of hours in a typical earth day. If the distance between these two planets is 4,000 parsecs, what was the average speed, in parsecs per hour, of the Starship Conundrum during this most recent voyage? Twice the number of hours in a typical earth day is 24*2=<<24*2=48>>48 hours. Eight hours less than twice the number of hours in a typical earth day is 48-8=<<48-8=40>>40 hours. If the distance between these two planets is 4,000 parsecs, then the average speed on this voyage was 4000/40=<<4000/40=100>>100 parsecs per hour. #### 100 The owner of a company needs to install a transformer to power his electrical equipment. He operates three units of machinery that require a running current of 40A each. These appliances require at least twice their running current for starting, and the transformer chosen must account for this. What is the minimum current load that his transformer of choice must be able to carry? Three units require a running current of 40A each for a total current load of 3*40A = <<3*40=120>>120A They require twice 120A for starting which is 2*120A = <<2*120=240>>240A which is the minimum current load that the transformer must be able to carry #### 240
